'IMPROVEMENT IN WATER-WHEELS.

TO ALL WHO-M IT MAYCONCERN:

Be itpknown that I, O. M..PIKE, of North Leverett, inv the lcounty ofFranklin, and State of Massachusetts, have invented a'new and usefulImprovement in Water-Wheels; and I do hereby declare that the followingis a.

full, clear, and exact description thereof, which will venable othersskilled in the art to make Aand use the same,i

reference being had to the 'aecorripanying` drawings, forming part ofthis specification, in which- Figure 1 is'a vertical section of myinvention, taken in the line'mx, iig. 2. Figure 2 is a plan or top viewof the same. I Similar letters of reference indicate correspondingparts. i This inyention relates to a. new and improved horizontalwater-wheel.

It consists in combining with the wheel a. slottedcylinder or drum,constructed and arranged in such a.

manner that the cylinder isinode 'to serve as a stop to the water, andeifetually prevent` any water from passingkthrough the wheel-case,except that which acts upon the buckets of the same. i' i M Intheaccompanying sheet of drawings, A represents a vertical shaft, and B thewheel, securely keyed thereon, vthe wheel being composed of a cylinderor drum, a, having buckets b on its exterior, of curvedY or spiral form.

`The wheel is partially enclosed within a case, C, the latter beingconcentric with the wheel, and extending Iaround about one-halfitscircumference.

On the wheel-shaft A, above the wheel, there is a toothed wheel, D,which gears into a corresponding wheel, E, on one end of a horizontalshaft, F, the latter having a wheel, Gr, precisely similar to E, on its`apposite end.

The wheel G gears into a. wheel, H, on'a shaft, I, the latter having adrum or hollow cylinder, Jupon it, the periphery ofjwhich is slotted ina direction parallel with its shaft or axis, as. shown at c; said slotsbeing at such n. distance apart as to admit of the buckets, passingthrough them as the' wheel rotates, (see fig. l.)

The periphery'of the drum J cornplet'ely closes the end of the case O,and joining the chute K, through which the water enters the case, andelfectually prevents any water passing out of the case at that point.All the water, therefore, that enters the case rixust act upon thebuckets; there can, be no other escape for it, except in its regularpassage" through the case. Y

The drum or cylinder J is rotated from the wheel-shaft,'by means of Vthe .gearing described, so that the upper ends of tlie'hncket b willenter. a slot, c, as they reach the inner side of the drum or cylinderJ. It will be seen, therefore, that said drum or cylinder serves as astop for the water, and insures the full force or actio ofthe sameagainst the buckets, so that a'large percentage of the power of thewater is obtained.

Having'thus described my invention, I claim as new, and desire` tosecure by Letters Patentv The rotary slotted drum or cylinder J, incombination with the wheel B andl case C, all constructed and arrangedto operate in the manner substantially as and for the` purpose setforth;

O. M. PIKE.
